GOTToN-TRAMPER.

To all whom it may concern;

Be it known that I, ERNST A. H. JACOB,

a citizen of the Republic of Germany, re-

siding at San Antonio, in the county of Bexarand State of Texas, have invented a new and useful Cotton-Tramper, of which the following is a specification. I

The device'forming the subject matter of i this application is a cotton tramper of that being provided for feeding the cotton into general type in which a vertically moving plunger operatesm a bahng trunk, means the trunk below the plunger.

One object of the invention is to provide a novel mechanism for operating the plunger.

Another object of the invention is to provide novel means whereby the feeding mechthe scope of what is claimed, changes falling within the skill of a mechanic, may be made without departing from the spirit of the invention or placing the utility thereof in jeopardy.

Specification of Letters Patent. Putg t d S t section, taken on the line 7 .-7

frame 1 is supplied with guides 3'in which a plunger, denoted generally by the numeral 4: is mounted for vertical reciprocation, the

plunger l including a foot 5 operating in the ballng trunk 2. The plunger t-includes a bar 6 and a bar 7 connected by pins 8, the bars and 7, together with the pins 8 constituting a double-sided rack. The bar 7 carries a plate9, coacting with ahopper 28 herelnafter described, to prevent the cotton 1n the hopper from passing into the ba'ling trunlr at times during the operation of the machme, as Wlll be described more fully hereinafter. I

The double-sidedrack 6 7 -8 coeperates with a pinion 10 carried by asha-ft .11 journaled in the upper end of a radius arm 12, mounted at its lower end to swing transversely, on a support 14, in the form of a horizontal rod carried by a block 15 mounted on the frame'l. to the shaft 11 and meshes into a pinion 17 v 7 1920.1 Application filed August 25, 1919. Serial No. 319,556. V

A gear wheel 16 issecured I on the hub 18 of a gear wheel 19, the hub 18 and the gear wheel being journaled on the support 14, and being held thereon by "a set ries pulleys 24:," one of which isfiired, the

other of which is loose, the pulleys 24: coacting'with a belt 25 engaging a pulley 26 on a line shaft 27.

The hopper 28, hereinbefore alluded to,

discharges into the baling trunlr2, adjacent thetop. of the baling trunk.

A shaft 2951sfixed in the hopper 28 andin the fr'amelf and extendslengthwise of thehopper. The

numeral 31 denotes a drum operating i'nlthe hopper, the drum including heads 30 and a shell 32, the heads 30 of the drum ,beinglrotatably mounted onfthe shaft 29,"one head carrying a sleeve 33. to which a beveled gear wheel '34 is attached. The beveled gear Wheel 34smeshes into a beveled pinion 35 011 a shaft 36 mounted to rotate in bearings 37 r carried, by the. frameIL The shaft'36 provided with a fixed pulley 38' and with a, loose pulley 39, the pulleys coeperating'with' a belt 40 engaginga'pulley 4l on the line shaft 27. I p V The frame of the machine carries a guide 42 in which a rod 43 is mounted to recipro oate. The rod 43 has an abutment 44. A.

helical compression spring 45 surrounds a portion of the rod 43 and is located between the abutment 44 and the guide 42, the function of the spring being to move the rod'43 lengthwise in one direction.

of the belt 40. The structure above described constitutes a part of a belt shifter, as

will be understood readily when the operation of the device is gone into. One end of the rod 43 is pivoted at 47 to one'a'rm of a bell crank lever 48 fulcrumed at 49 on the frame'l, the other arm of the bell crank lever being loosely received in a notch 50 formed in a slide rod'51 mounted for 'endwise reciprocation in a guide 52, carried by the frame 1. The inner end of the slide rod 51 carries a roller 53 adapted to coact with an actuating strip 54 constituting a part of the plunger 4, the actuating strip including a beveled end 55.

The heads or ends of the drum 31 are provided with guides 56. Carriers 57 in the parts 57. 35 I form of bars, extend longitudinally of the drum within the same, and are supplied with inwardly projecting ends 58 mounted to slide between the guides 56. The carriers 57 are provided with teeth 59 extended outwardly through the shell 32 of the drum and slidable therein; Disks 60, are mounted eccentrically on the fixed shaft 29 and are supplied with flanges 61 defining a cam track receiving rollers 62 on the ends 58 of the In practical operation, rotation is imparted to the shaft 22 from the line shaft 27 byway of the pulley 26, the belt 25 and one of the pulleys 24. VVhen the shaft 22 is rotated, the pinion 21 is rotated, rotation being imparted to the gear wheel 19 and from the gear wheel 19 motion is trans mitted to the shaft 11 by way of the pinion- 17 and the gear wheel 16, \Vhen the shaft 11 is rotated, the pinion 10 cotiperates with the rack formed by the pins 8. The rack and the plunger 4 are operated, the pinion 10 coiiperating with one side of'the rack and then with the other side of the rack, it, being possible for they pinion 10 to pass from one side of the rack to the other across theends .of the rackbecause the radius arm 12 is mounted for swinging movement on the 'me mber l l. During the timethat the radius arm 12 is swingingas aforesaid, the gear wheel 16011 the shaft 11 remains 111 mesh with thepinlon 17 on the hub 18 of the gear wheel 19."A continuous movement, therefore is imparted-to the pinion 10 and this movement is, communicated to the plunger 4 by way of the rack 8, the plunger recipro catmg cont nuously, and the foot 5 of the plunger operating in the trunk 2.

During the major portion ofthe upward stroke of the plunger 4, and during the ma or portion of the downward stroke there- The rod; 43. carries fingers 46-l0cated on opposite sides plunger 4 is at the upper end of its'travel,

of, the rotary feeder, comprising the drum 31 and cooperating parts, is atrest, because the belt 40 is engaged with the loose pulley 39. Asthe plunger 4 moves toward the end 7 of its upward stroke," the strip 54 cooperates with the roller 53 on the end of the member 51, and the member 51 is thrust outwardly, the bell crank lever 48 being tilted on its fulcrum 49 and the rod 43 being retracted against the action of the spring 45, the

- fingers 46 on the'rod43 sliding the belt 40 over from the loose pulley 39 to the fixed pulley 38 on the shaft 36. Rotation, therefore, is imparted to the shaft 36 while the and for a short time, while the plunger is beginning its downward movement. V

lVhen the shaft 36 is rotated as aforesaid, the beveled pinions 35 and 34 impart .rotation to the drum 31. When the drum 31 is rotated, the rollers 62 on the ends 58 of the members 57 ride in the cam tracks 61 of the i disks 60 which are fixed to the shaft29, this latter element being fixed, it being recalled; It will be obvious that the cooperation bewill be advanced and retracted, the cotton being swept from the hopper 28 into the baling trunk 2 during the time that the plunger 4 is completing its upward stroke s v tween the parts is such that the fingers v and beginning its downward stroke, it being recalled that it is during this interval'that the strip 54 engages the roller 53 on the slide rod 51- and forces the same outwardly,'asi aforesaid, to shift'the belt 40, fromtheloose pulley 39 on the shaft '36 'to the fixed pulley 38 thereon. When the roller 53 on the in ner end of the slide rod 51 is no longer in engagement with the strip ,54, then the; spring 45 reasserts itself, and moves the rod 43 to'the left (Fig.1), the fingers 46 onthe rod shifting the belt 40,]from the fixed pulley V 38 to the loose pulley 39 and causing the rotation of the feeding drum 31 to stop. As 7 the plunger 4 moves downwardly, th e plate 9 constitutes a closure forthe innerside of the hopper 28 and prevents the cottonvfrom I I moving against'the side of the descending plunger 4. The feeding mechanism including the drum 31, is'idle during the major upwardly or' downwardly? The "rotary o feeder shown in Figs. 6 and 7 beginsto turn at the time that the foot 5 of the plunger 4 arrives at the bottom of the hopper 28 on foot has arrived nearly at the bottom of the hopper on the downstroke;

Having thus described the invention what is claimed is a trunk; a plunger mountedto reciprocate in the frame and cooperating with the trunk, the plunger including a double-sided freeended rack; a radius arm mounted at its lower end to oscillate in an are on the frame; a pinion carried by the upper end of the radius arm and cooperating With the rack; and means for rotating the pinion.
